WINDOW SCREEN.

Application filed May 8,

To all whom it may concern:

Be it known that I, WILLIAM H. KUHNE, a citizen of the United States, residing at Safety Harbor, in thecounty of Pinellas and State of Florida, have invented certain new and useful Improvements in a Window Screen, of which the following is a specification.

This invention relates to window screens and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a window screen structure. including tracks adapted to be applied to the inner surfaces of the upright sides of a window frame and frames mounted for movement along the tracks. The said frames are adapted to retain screens or glazed sashes and the tracks are composed of sections, some of which are. fixed to the window frame and other of the the sections are pivotally mounted whereb they may be swung out of alignment witli the fixed sections and the said frames may be readily removed from the tracks without detaching the tracks from the window frame.

In the accompanying drawings Figure 1 is a side elevationof a window frame with the screen applied.

Figure 2 includes views of the sections of one of the guide tracks.

Figure 3 is a fragmentary side elevation of the corner portion of one of the supplemental frames and guide track.

Figure 4 is a horizontal sectional view thereof cut on the line 4-4 of Figure 3.

Figure 5 is a transverse sectional view thereof cut on the line 55 of Figure 3.

Figure 6 is an enlarged side elevation of the lower corner of one of the supplemental frames.

Figure 7 is a transverse sectional view thereof out on the line 77 of Figure 6.

Figure 8 is a fragmentary view of the corner portion of one of the screen frames.

Figure 9 is a transverse sectional view of the screen frame, the section being taken approximately on the line 99 of Figure 8.

Figure 10 is an enlarged detailed side elevation of one of the sections of the guide track. Figure 11 is a side edge elevation of the same.

Figure 12 is a transverse sectional view of the track section cut on the line 12-12 of Figure 10.

The window screen structure includes two 1924. Serial No. 711,348.

guide tracks 11 which are mounted at the inner surfaces of the side. uprights ofthe main window frame. Each guidetrack 1ncludes one intermediate section 3 which is pivoted at a pointmidway between its ends as indicated at 4 in Figure 2, to the side of the window frame 2. The section Sis provided with spaced guide channels 5 disposed in spaced parallelism. Thetrack also in-v cludes two terminal or endsections 6 which frame 2 and the frames 7 are composed of spaced side strips 8 which are connected with each other by means of rivets 9 passing through flanges 8 and strips 10 are slidably mounted between the strips 8. The strips 10 are provided with transversely disposed slots 11 which receive rivets 12, the said rivets being secured to the flanges 8. The extended edge portions of the strips 10 are adapted to move along the guides 5 of the track "sections. The space between the upper edges of the strips'8 of the upper frames 7 is closed by a cap strip 15 as best shown in Figure 5 of the drawing. A screen frame 13 may be inserted in each of the frames 7 or should it be desired sash frames and a glass panel may be inserted ,in the frames 7 in lieu of the screen frames 13. The lower frame 7 is provided at its upper portion with a catch member 14 adapted to engage the lower rail of the upper frame 7 when the said frames are extended within the window frame 2 as shown in Figure 1 of the drawing and whereby the upper frame 7 is held at an elevated position be tween the guide tracks 1. When it is desired to remove the frames 7 from the tracks 1 and the window frame 2, said frames 7 are moved into the guides 5 of the intermediate track sections 3 and then the said sections are swung, substantially to the position as shown in Figure 2 of the drawings when Ill) reinserted between the tracks and within the Window frame 2. When the sections are in alignment With the terminal sections 6 the frames 7 may move the full length of the tracks 1 and When the strips 10 of the frames 7 bridge the joints between the intermediate sections 3 and the terminal sections 6 of the tracks 1, the said sections are held in vertical alignment with each other;

From the foregoing description taken in conjunction with *the aceompai'nyirig drawings it Willbe seenthat a window "screen structure is provided and in which 'the screen frames 01' the sash frames ma be readily and-easily detached f'roin the window frame for the purpose of cleaning, storage or theflike Also the stripsof the slidable frame effectually close the window o'fpening and-prevent the passage of flies or mosquitoes through the window "open ings. c

Having thus described the invention, What I"claim'is:- i

1. A window 'screen' structur'e comprising yPlVOtBd track sections being longer verticallfy than the frames and the frames being longer vertically than the fixed track sections. v I

2. A WlIldOW'SOIQGH structure"comprising tracks applied to "tlie-s'ides of "the Window frame, each track'including an intermediate pivoted section and terminal fixed sections, said sections having beveled adjacent ends, all .of the sections being provided with spaced Jgui'de ays-, 'f-r'ames :locatedbetweeh the tracks, said frames being provided at their sides with strips, said strips having transversely "disposed slots and rivets carried by the frames and'passing through said slots. a

'In test-imbny whereof 'I aflix my signature.
